Description
The Idaho Department of Environmental Quality (DEQ) administers State Revolving Fund (SRF) construction loans to help qualified Idaho drinking water and wastewater systems improve their facilities. Supported in part by U.S. Environmental Protection Agency funding, the program finances project planning, design, and construction through below-market-rate loans. Qualifying disadvantaged systems may receive partial principal forgiveness and extended repayment terms.
DEQ ranks projects according to public health and environmental concerns, system sustainability, and compliance with state and federal regulations. Readiness to proceed helps determine the final fundable list in the annual Intended Use Plans. The program also encourages green infrastructure, water conservation, energy efficiency, environmentally innovative activities, and cyber-informed engineering through its Letter of Interest process.
